BACKGROUND

A robot is a mechanical or virtual artificial agent, usually anelectromechanical machine that is guided by a computer program orelectronic circuitry, and thus a type of an embedded system. Robots havebeen widely used today for wide range of industries (e.g., oil drilling,factory automation, underwater discovery, etc.). Conventional robotsrequire dedicated and special purpose hardware/software resource whichimpose significant limitation. Conventional robots lacks flexibility andare incapable to adapt when environment, application, and event changes.

DETAILED DESCRIPTION

Disclosed herein are methods, systems, and apparatuses for on-demandrobot virtualization. Robots may be instantiated on-demand and may beadaptive to an environment, application, or event change. FIG. 1illustrates an exemplary system 100 for on-demand robot virtualization.Server 101 may be communicatively connected via network 103 to sensor104, robot 106, or mobile device 108. Examples of mobile device 108 maybe a tablet, smartphone, or laptop. In system 100, as discussed herein,there may be multiple virtual machines located within different devices,such as virtual machine 102, virtual machine 107, or virtual machine109. Virtual machines may encapsulate a complete set of virtual hardwareresources, including an operating system and all its applications,inside a software package. Virtual machines may be different identitiesthat comprise functions for that identity (e.g., police officer, bankteller) Sensor 104 may be an accelerometer, gyroscope, magnetometer,light sensor, temperature sensor, motion sensor, or GPS, among others.Sensor 104 may be located in or outside a structure, located in or onrobot 106, located in or on mobile device 108, or the like.

Robot 106 may be any type of robot (e.g., bipedal or quadrupedal;autonomous or non-autonomous), but preferably a humanoid robot. Ingeneral, humanoid robots may have a torso, a head, two arms, and twolegs, but it is contemplated that some forms of humanoid robots maymodel only part of the body, such as from the waist up or just anarm(s). A robot may be defined an actuated mechanism programmable in twoor more axes with a degree of autonomy, moving within its environment,to perform intended tasks. See ISO 8373:2012(en) (incorporated byreference in its entirety). An autonomous robot is a robot that performsbehaviors or tasks with a high degree of autonomy, which is particularlydesirable in fields such as space exploration, household maintenance(such as cleaning), waste water treatment and delivering goods andservices. A fully autonomous robot may: gain information about theenvironment; work for an extended period without human intervention;move a part of itself throughout its operating environment without humanassistance; and avoid situations that are harmful to people, property,or itself unless those are part of its design specifications.

FIG. 2 illustrates an exemplary method for on-demand robotvirtualization. At step 111, server 101 may receive informationassociated with a location. For example information associated with alocation may include information from sensor 104 near the location,information from mobile device 108 (e.g., request for use of robot 106in a particular manner—emergency or errand), information from robot 106(e.g., sensor information or request based on determined status oflocation), or other information (e.g., time, date). At step 112, sever101 may determine, based on the information, a type of event (e.g.,robbery, user request, medical emergency, fire, etc.). The event may bewithin a predetermined category which indicates that the event isappropriate for a robot (i.e., robot actionable event). A robotactionable event may be predetermined by a user. A robot actionableevent may be based on a certain threshold level being met or othertriggers. In a first example, a threshold level may include a detectednumber of people in an area. The detected number of people may indicatea possible need for a crowd control operation by robot 106 or mayindicate a possible need for an extra cashier to assist at customercheckout. In the first example, it is contemplated that there may beseveral considerations made in addition to the number of people, such aslocation of event or time of day. In a second example, information mayinclude a number of people, body language or facial expressions of thepeople, and number of balloons. For this example, consideration of theinformation may indicate that a celebration (e.g., birthday party) isoccurring and trigger robot 106 to be a clown (e.g., juggles or inflatesballoons).

At step 113, as eluded to in step 112, based on the event, server 101may determine desired specifications of robot 106. Server 101 may have alist of minimum to ideal specifications for robot 106 to have for thetype of event. Revisiting the first example above, robot 106 may need tobe a threshold height in order to be visible by the crowd, havethreshold audio capabilities in order to be heard by the crowd, andthreshold communication capability (e.g. SMS, MMS, voice over IP, etc.)in order to coordinate with other robots or people that may be assistingor desire to assist with crowd control. Specifications desired for robot106 may be software or hardware related, which may include softwareversions, battery (e.g., current battery life, battery power output,estimated battery life to perform anticipated actions, etc.), antennas,processor speed, amount of memory, speed of robot 106, payload capacity(e.g., carrying a person or thing), types of sensors of robot 106,lights, actuators, or the like. The specifications may also apply tomobile device 108.

With continued reference to FIG. 1, at step 114, virtual machine 102 maybe generated or selected based on the event, based on the controlfunctions, or based on the specifications (desired or actual) of robot106. At this step 114, server 101 may consider the control functions(e.g., the hardware or software functions used to perform certainactions, such as lift an object) to select or generate an appropriatevirtual machine 102. At step 115, instructions are provided to activatevirtual machine 102 to control robot 106.

There are several scenarios in which the virtual machine 102, 107, or109, such as in step 114 and step 115, may be used for on-demand robotvirtualization. In a first scenario, virtual machine 102 may remotelycontrol robot 106. Server 101 may turn off or switch the virtualmachines to correspond to different events (e.g., police officer virtualmachine may be switched to cashier virtual machine). In a secondscenario, virtual machine 107 may reside on robot 106 (e.g., aninstalled instance of virtual machine 107). Virtual machine 107 may beone of a plurality of virtual machines on robot 106 that is activated asneeded (e.g., step 115). The other virtual machines on robot 106 may bein memory as file, but not an installed instance. Virtual machine 107may be in a zipped or non-installed state and be alerted to uninstallvia step 115 and become an installed instance. Server 101 may transfervirtual machine 107 to robot 106 after the control function isdetermined. In a third scenario, server 101 may send the software forvirtual machine 107, but in this scenario robot 106 may be used to carrythe software of virtual machine 107 to another robot (not shown) that isthe ultimate attended user of the virtual machine 107. Robot 106 mayphysically connect (e.g., USB) with the other robot or wirelesslyconnect with the other robot. This method may be used based on securityconcerns and budgetary reasons (e.g., only one robot has sufficientsecurity to download and transmit in order to keep costs down). Signalstrength may help determine selected virtual machines or how much of anidentity is downloaded. For example, there may be different levels of anidentity downloaded based on signal strength at current location ofrobot 106 or anticipated signal strength for an area robot 106 willtraverse.

Additional scenarios associated with virtual machines are discussedbelow. In a fourth scenario, server 101 may send the software forvirtual machine 107 to mobile device 108, but in this scenario mobiledevice 108 may be used to carry the software of virtual machine 107 torobot 106 that is the ultimate intended user of virtual machine 107(e.g., installed instance of virtual machine 107). Mobile device 108 maybe physically connected (e.g., USB—universal serial bus) with robot 106,wirelessly connected with robot 106, or a memory of mobile device 108may be inserted into robot 106. The user associated with mobile device108 may be authorized to instruct/direct robot 106. In a fifth scenario,server 101 may send or activate virtual machine 109. Virtual machine 109may also already be present on mobile device 108 and activated by anassociated user of mobile device 108. In this scenario, mobile device108 may be used to wirelessly connect with robot 106 and use virtualmachine 109 to control robot 106. Robot 106 may act as a physicalextension of virtual machine 109 on mobile device 108. Exemplary usecases for the mobile device 108 scenarios (and other scenarios) mayinclude consumer use of robot 106 in pushing a grocery cart or mowing alawn (e.g., personal service robot). A consumer may pay to use robot 106in the scenarios discussed herein. The payment may be via websitepayments or convenient mobile payments (e.g., “mobile wallet” via nearfield communication—NFC). In emergency situations, payment may not beneeded just the dialing of 911 and communicatively connecting with robot106. Dialing 911 may connect mobile device to voice call with emergencypersonnel, but also may broadcast an emergency alert to nearby robots,which may assist in locating mobile device 108. Robot 106 mayautomatically report its location in this emergency situation. Mobiledevice 108 may be physically (e.g., wired/inserted) connected orwirelessly connected with robot 106 then 911 may be dialed to indicatean emergency. There may be a default emergency related virtual machine(e.g., police, fire) loaded on mobile device 108 or robot 106 for quickaccess.

Further considerations associated with on-demand robot virtualizationare discussed below. Robot 106, before installation of a virtualmachine, may have base level functions, such as responding to name ordigitally displaying information. As discussed herein, robots may bechanged from one identity to the next (e.g., police officer mode to bankteller mode). A display on robot 106 may communicate the mode (i.e.,virtualized function) based on text, a color, a picture, or video (e.g.,“POLICE OFFICER”). The display of robot 106 (not shown) may be locatedon forehead (or other portions of face), on back of head, torso (e.g.,chest), or back (e.g., upper back) of robot 106.

Location or detection of wireless signals may be used to help restrictfunctions and make robot 106 more secure. Geofences may be used create aboundary for the use of robot 106. A geofence is a virtual barrier.Programs that incorporate geo-fencing allow an administrator to set uptriggers so when a device enters (or exits) the boundaries defined bythe administrator, an action is taken, such as a SMS message is sent,email alert is sent, a siren goes off. In an example, if robot 106reaches a geofence boundary it may shutoff, move back towards the centerof the geofence, or otherwise stop moving. In another example, thegeofence may restrict robot 106 to a particular set of identities. Robot106 may have identity A and be allowed to use identity A in geofence Y(not shown), but not in geofence Z (not shown). So if robot 106 entersinto geofence Z, robot 106 may immediately shutdown. Alternatively, ifrobot 106 enters in geofence Z, robot 106 may be allowed in geofence Zwith identity A for a short period (e.g., 30 minutes). Once the periodis expired, robot 106 may shutdown, resort to a default identity andreturn to geofence Y, or a number of other alternatives. It iscontemplated that this may be particularly useful with jurisdictionalissues, for example with police or other public safety. Geofences may bedetermined based on the detection of wireless radio or light signals orGPS, among other things.

Wireless signaling technology (e.g., radio, infrared, ultrasonic) may beused to restrict the use of robot 106. A wireless technology may beselected based on a determined function. In an example, if robot 106 isin a mode as an assistant of a user associated with mobile device 106,then Bluetooth may be used to keep robot 106 from roaming away. But ifrobot 106 is in a mode as a security guard, WiFi may be used to keeprobot 106 in or near the building. If leaves the range of the wirelesstechnology it may trigger a shutdown, sending of an alert message, orthe like response.

A virtual machine (e.g., system virtual machine or process virtualmachine) is a software implementation of a machine (for example, acomputer) that executes programs like a physical machine. It iscontemplated herein that virtual machine 102, virtual machine 107, orvirtual machine 109 may be a self-contained identity (e.g., policeofficer, cashier, teacher, etc.) for robot 106. Terms identity or modeare generally used interchangeably herein. The methods, systems, andapparatuses discussed herein associated with on-demand robotvirtualization, in which designated functions (e.g., officer) areconstrained to robot 106, may make for a safer, more reliable, andefficient use of resources. Virtual robots are considered herein aswell. Virtual robot may be digital construction of a physical robot in avirtual world (e.g., Second Life). The virtual robot may interact and beaffected by other digital constructions (e.g., digital doors) just as itwould in a physical world.

Virtual machines can be isolated software containers, operatingindependent of other virtual machines. Such isolation can assist inrealizing virtual-machine-based virtual environments that can executeapplications and provide services with availability, flexibility, andsecurity, in some cases, surpassing those on traditional,non-virtualized systems. Virtual machines can encapsulate a complete setof virtual hardware resources, including an operating system and all itsapplications, inside a software package. Encapsulation can make virtualmachines quite portable and manageable. Indeed, virtual machines can behardware-independent, and can be portably provisioned and deployed onone of multiple different computing devices, operating systems, andenvironments. Indeed, depending on the availability of computing deviceswithin a cloud environment (e.g., server 101) a particular virtualmachine 102 may be provisioned on any one (or multiple) of the devicesincluded in cloud environment 101.

In some instances, a virtual machine manager (not shown) may be providedin connection with a cloud computing system (e.g., 101) (or other systemhosting virtual infrastructure). Virtual machine managers, orhypervisors, may be implemented as software- and/or hardware-based toolsused in the virtualization of hardware assets (i.e., as virtual machines102) on one or more host computing devices (e.g., server 101). A virtualmachine manager may be used to run multiple virtual machines (e.g.,102), including virtual machines with different guest operating systems,on one or more host computers (e.g., server 101). The virtual machinemanager may provide a shared virtual operating platform for multiplevirtual appliances and guest operating systems and enable a plurality ofdifferent virtual machines (and guest operating systems) to beinstantiated and run on computing devices and hardware hosting virtualinfrastructure (e.g., robot 1061 or mobile device 108). Further, virtualmachine managers, in some instances may be run natively, or as “baremetal,” directly on host computing devices' hardware to control thehardware and to manage virtual machines provisioned on the host devices.In other instances, “hosted” virtual machine managers may be providedthat is run within the operating system of another host machine,including conventional operating system environments. Although virtualmachine is discussed the methods systems are applicable to applicationsin one operating system environment. Lastly, virtual component can beprogrammed to perform application specific functions that may beassociated with microcontroller, sensor, motors, actuators, lighting, orradio frequency identification (RFID).

FIG. 4 illustrates a functional block diagram depicting one example ofan LTE-EPS network architecture 400 that may implement on-demandvirtualization of robots. In particular, the network architecture 400disclosed herein is referred to as a modified LTE-EPS architecture 400to distinguish it from a traditional LTE-EPS architecture.

An example modified LTE-EPS architecture 400 is based at least in parton standards developed by the 3rd Generation Partnership Project (3GPP),with information available at www.3gpp.org. In one embodiment, theLTE-EPS network architecture 400 includes an access network 402, a corenetwork 404, e.g., an EPC or Common BackBone (CBB) and one or moreexternal networks 406, sometimes referred to as PDN or peer entities.Different external networks 406 can be distinguished from each other bya respective network identifier, e.g., a label according to DNS namingconventions describing an access point to the PDN. Such labels can bereferred to as Access Point Names (APN). External networks 406 caninclude one or more trusted and non-trusted external networks such as aninternet protocol (IP) network 408, an IP multimedia subsystem (IMS)network 410, and other networks 412, such as a service network, acorporate network, or the like.

Access network 402 can include an LTE network architecture sometimesreferred to as Evolved Universal mobile Telecommunication systemTerrestrial Radio Access (E UTRA) and evolved UMTS Terrestrial RadioAccess Network (E-UTRAN). Broadly, access network 402 can include one ormore communication devices, commonly referred to as UE 414, and one ormore wireless access nodes, or base stations 416 a, 416 b. Duringnetwork operations, at least one base station 416 communicates directlywith UE 414. Base station 416 can be an evolved Node B (e-NodeB), withwhich UE 414 communicates over the air and wirelessly. UEs 414 caninclude, without limitation, wireless devices, e.g., satellitecommunication systems, portable digital assistants (PDAs), laptopcomputers, tablet devices and other mobile devices (e.g., cellulartelephones, smart appliances, and so on). UEs 414 can connect to eNBs416 when UE 414 is within range according to a corresponding wirelesscommunication technology.

UE 414 generally runs one or more applications that engage in a transferof packets between UE 414 and one or more external networks 406. Suchpacket transfers can include one of downlink packet transfers fromexternal network 406 to UE 414, uplink packet transfers from UE 414 toexternal network 406 or combinations of uplink and downlink packettransfers. Applications can include, without limitation, web browsing,VoIP, streaming media and the like. Each application can pose differentQuality of Service (QoS) requirements on a respective packet transfer.Different packet transfers can be served by different bearers withincore network 404, e.g., according to parameters, such as the QoS.

Core network 404 uses a concept of bearers, e.g., EPS bearers, to routepackets, e.g., IP traffic, between a particular gateway in core network404 and UE 414. A bearer refers generally to an IP packet flow with adefined QoS between the particular gateway and UE 414. Access network402, e.g., E UTRAN, and core network 404 together set up and releasebearers as required by the various applications. Bearers can beclassified in at least two different categories: (i) minimum guaranteedbit rate bearers, e.g., for applications, such as VoIP; and (ii)non-guaranteed bit rate bearers that do not require guarantee bit rate,e.g., for applications, such as web browsing.

In one embodiment, the core network 404 includes various networkentities, such as MME 418, SGW 420, Home Subscriber Server (HSS) 422,Policy and Charging Rules Function (PCRF) 424 and PGW 426. In oneembodiment, MME 418 comprises a control node performing a controlsignaling between various equipment and devices in access network 402and core network 404. The protocols running between UE 414 and corenetwork 404 are generally known as Non-Access Stratum (NAS) protocols.

For illustration purposes only, the terms MME 418, SGW 420, HSS 422 andPGW 426, and so on, can be server devices, but may be referred to in thesubject disclosure without the word “server.” It is also understood thatany form of such servers can operate in a device, system, component, orother form of centralized or distributed hardware and software. It isfurther noted that these terms and other terms such as bearer pathsand/or interfaces are terms that can include features, methodologies,and/or fields that may be described in whole or in part by standardsbodies such as the 3GPP. It is further noted that some or allembodiments of the subject disclosure may in whole or in part modify,supplement, or otherwise supersede final or proposed standards publishedand promulgated by 3GPP.

According to traditional implementations of LTE-EPS architectures, SGW420 routes and forwards all user data packets. SGW 420 also acts as amobility anchor for user plane operation during handovers between basestations, e.g., during a handover from first eNB 416 a to second eNB 416b as may be the result of UE 414 moving from one area of coverage, e.g.,cell, to another. SGW 420 can also terminate a downlink data path, e.g.,from external network 406 to UE 414 in an idle state, and trigger apaging operation when downlink data arrives for UE 414. SGW 420 can alsobe configured to manage and store a context for UE 414, e.g., includingone or more of parameters of the IP bearer service and network internalrouting information. In addition, SGW 420 can perform administrativefunctions, e.g., in a visited network, such as collecting informationfor charging (e.g., the volume of data sent to or received from theuser), and/or replicate user traffic, e.g., to support a lawfulinterception. SGW 420 also serves as the mobility anchor forinterworking with other 3GPP technologies such as universal mobiletelecommunication system (UMTS).

At any given time, UE 414 is generally in one of three different states:detached, idle, or active. The detached state is typically a transitorystate in which UE 414 is powered on but is engaged in a process ofsearching and registering with network 402. In the active state, UE 414is registered with access network 402 and has established a wirelessconnection, e.g., radio resource control (RRC) connection, with eNB 416.Whether UE 414 is in an active state can depend on the state of a packetdata session, and whether there is an active packet data session. In theidle state, UE 414 is generally in a power conservation state in whichUE 414 typically does not communicate packets. When UE 414 is idle, SGW420 can terminate a downlink data path, e.g., from one peer entity 406,and triggers paging of UE 414 when data arrives for UE 414. If UE 414responds to the page, SGW 420 can forward the IP packet to eNB 416 a.

HSS 422 can manage subscription-related information for a user of UE414. For example, tHSS 422 can store information such as authorizationof the user, security requirements for the user, quality of service(QoS) requirements for the user, etc. HSS 422 can also hold informationabout external networks 406 to which the user can connect, e.g., in theform of an APN of external networks 406. For example, MME 418 cancommunicate with HSS 422 to determine if UE 414 is authorized toestablish a call, e.g., a voice over IP (VoIP) call before the call isestablished.

PCRF 424 can perform QoS management functions and policy control. PCRF424 is responsible for policy control decision-making, as well as forcontrolling the flow-based charging functionalities in a policy controlenforcement function (PCEF), which resides in PGW 426. PCRF 424 providesthe QoS authorization, e.g., QoS class identifier and bit rates thatdecide how a certain data flow will be treated in the PCEF and ensuresthat this is in accordance with the user's subscription profile.

PGW 426 can provide connectivity between the UE 414 and one or more ofthe external networks 406. In illustrative network architecture 400, PGW426 can be responsible for IP address allocation for UE 414, as well asone or more of QoS enforcement and flow-based charging, e.g., accordingto rules from the PCRF 424. PGW 426 is also typically responsible forfiltering downlink user IP packets into the different QoS-based bearers.In at least some embodiments, such filtering can be performed based ontraffic flow templates. PGW 426 can also perform QoS enforcement, e.g.,for guaranteed bit rate bearers. PGW 426 also serves as a mobilityanchor for interworking with non-3GPP technologies such as CDMA2000.

Within access network 402 and core network 404 there may be variousbearer paths/interfaces, e.g., represented by solid lines 428 and 430.Some of the bearer paths can be referred to by a specific label. Forexample, solid line 428 can be considered an S1-U bearer and solid line432 can be considered an S5/S8 bearer according to LTE-EPS architecturestandards. Without limitation, reference to various interfaces, such asS1, X2, S5, S8, S11 refer to EPS interfaces. In some instances, suchinterface designations are combined with a suffix, e.g., a “U” or a “C”to signify whether the interface relates to a “User plane” or a “Controlplane.” In addition, the core network 404 can include various signalingbearer paths/interfaces, e.g., control plane paths/interfacesrepresented by dashed lines 430, 434, 436, and 438. Some of thesignaling bearer paths may be referred to by a specific label. Forexample, dashed line 430 can be considered as an S1-MME signalingbearer, dashed line 434 can be considered as an S11 signaling bearer anddashed line 436 can be considered as an S6a signaling bearer, e.g.,according to LTE-EPS architecture standards. The above bearer paths andsignaling bearer paths are only illustrated as examples and it should benoted that additional bearer paths and signaling bearer paths may existthat are not illustrated.

Also shown is a novel user plane path/interface, referred to as theS1-U+ interface 466. In the illustrative example, the S1-U+ user planeinterface extends between the eNB 416 a and PGW 426. Notably, S1-U+path/interface does not include SGW 420, a node that is otherwiseinstrumental in configuring and/or managing packet forwarding betweeneNB 416 a and one or more external networks 406 by way of PGW 426. Asdisclosed herein, the S1-U+ path/interface facilitates autonomouslearning of peer transport layer addresses by one or more of the networknodes to facilitate a self-configuring of the packet forwarding path. Inparticular, such self-configuring can be accomplished during handoversin most scenarios so as to reduce any extra signaling load on the S/PGWs420, 426 due to excessive handover events.

In some embodiments, PGW 426 is coupled to storage device 440, shown inphantom. Storage device 440 can be integral to one of the network nodes,such as PGW 426, for example, in the form of internal memory and/or diskdrive. It is understood that storage device 440 can include registerssuitable for storing address values. Alternatively or in addition,storage device 440 can be separate from PGW 426, for example, as anexternal hard drive, a flash drive, and/or network storage.

Storage device 440 selectively stores one or more values relevant to theforwarding of packet data. For example, storage device 440 can storeidentities and/or addresses of network entities, such as any of networknodes 418, 420, 422, 424, and 426, eNBs 416 and/or UE 414. In theillustrative example, storage device 440 includes a first storagelocation 442 and a second storage location 444. First storage location442 can be dedicated to storing a Currently Used Downlink address value442. Likewise, second storage location 444 can be dedicated to storing aDefault Downlink Forwarding address value 444. PGW 426 can read and/orwrite values into either of storage locations 442, 444, for example,managing Currently Used Downlink Forwarding address value 442 andDefault Downlink Forwarding address value 444 as disclosed herein.

In some embodiments, the Default Downlink Forwarding address for eachEPS bearer is the SGW S5-U address for each EPS Bearer. The CurrentlyUsed Downlink Forwarding address” for each EPS bearer in PGW 426 can beset every time when PGW 426 receives an uplink packet, e.g., a GTP-Uuplink packet, with a new source address for a corresponding EPS bearer.When UE 414 is in an idle state, the “Current Used Downlink Forwardingaddress” field for each EPS bearer of UE 414 can be set to a “null” orother suitable value.

In some embodiments, the Default Downlink Forwarding address is onlyupdated when PGW 426 receives a new SGW S5-U address in a predeterminedmessage or messages. For example, the Default Downlink Forwardingaddress is only updated when PGW 426 receives one of a Create SessionRequest, Modify Bearer Request and Create Bearer Response messages fromSGW 420.

As values 442, 444 can be maintained and otherwise manipulated on a perbearer basis, it is understood that the storage locations can take theform of tables, spreadsheets, lists, and/or other data structuresgenerally well understood and suitable for maintaining and/or otherwisemanipulate forwarding addresses on a per bearer basis.

It should be noted that access network 402 and core network 404 areillustrated in a simplified block diagram in FIG. 4. In other words,either or both of access network 402 and the core network 404 caninclude additional network elements that are not shown, such as variousrouters, switches and controllers. In addition, although FIG. 4illustrates only a single one of each of the various network elements,it should be noted that access network 402 and core network 404 caninclude any number of the various network elements. For example, corenetwork 404 can include a pool (i.e., more than one) of MMEs 418, SGWs420 or PGWs 426.

In the illustrative example, data traversing a network path between UE414, eNB 416 a, SGW 420, PGW 426 and external network 406 may beconsidered to constitute data transferred according to an end-to-end IPservice. However, for the present disclosure, to properly performestablishment management in LTE-EPS network architecture 400, the corenetwork, data bearer portion of the end-to-end IP service is analyzed.

An establishment may be defined herein as a connection set up requestbetween any two elements within LTE-EPS network architecture 400. Theconnection set up request may be for user data or for signaling. Afailed establishment may be defined as a connection set up request thatwas unsuccessful. A successful establishment may be defined as aconnection set up request that was successful.

In one embodiment, a data bearer portion comprises a first portion(e.g., a data radio bearer 446) between UE 414 and eNB 416 a, a secondportion (e.g., an S1 data bearer 428) between eNB 416 a and SGW 420, anda third portion (e.g., an S5/S8 bearer 432) between SGW 420 and PGW 426.Various signaling bearer portions are also illustrated in FIG. 4. Forexample, a first signaling portion (e.g., a signaling radio bearer 448)between UE 414 and eNB 416 a, and a second signaling portion (e.g., S1signaling bearer 430) between eNB 416 a and MME 418.

In at least some embodiments, the data bearer can include tunneling,e.g., IP tunneling, by which data packets can be forwarded in anencapsulated manner, between tunnel endpoints. Tunnels, or tunnelconnections can be identified in one or more nodes of network 400, e.g.,by one or more of tunnel endpoint identifiers, an IP address and a userdatagram protocol port number. Within a particular tunnel connection,payloads, e.g., packet data, which may or may not include protocolrelated information, are forwarded between tunnel endpoints.

An example of first tunnel solution 450 includes a first tunnel 452 abetween two tunnel endpoints 454 a and 456 a, and a second tunnel 452 bbetween two tunnel endpoints 454 b and 456 b. In the illustrativeexample, first tunnel 452 a is established between eNB 416 a and SGW420. Accordingly, first tunnel 452 a includes a first tunnel endpoint454 a corresponding to an S1-U address of eNB 416 a (referred to hereinas the eNB S1-U address), and second tunnel endpoint 456 a correspondingto an S1-U address of SGW 420 (referred to herein as the SGW S1-Uaddress). Likewise, second tunnel 452 b includes first tunnel endpoint454 b corresponding to an S5-U address of SGW 420 (referred to herein asthe SGW S5-U address), and second tunnel endpoint 456 b corresponding toan S5-U address of PGW 426 (referred to herein as the PGW S5-U address).

In at least some embodiments, first tunnel solution 450 is referred toas a two tunnel solution, e.g., according to the GPRS Tunneling ProtocolUser Plane (GTPv1-U based), as described in 3GPP specification TS29.281, incorporated herein in its entirety. It is understood that oneor more tunnels are permitted between each set of tunnel end points. Forexample, each subscriber can have one or more tunnels, e.g., one foreach PDP context that they have active, as well as possibly havingseparate tunnels for specific connections with different quality ofservice requirements, and so on.

An example of second tunnel solution 458 includes a single or directtunnel 460 between tunnel endpoints 462 and 464. In the illustrativeexample, direct tunnel 460 is established between eNB 416 a and PGW 426,without subjecting packet transfers to processing related to SGW 420.Accordingly, direct tunnel 460 includes first tunnel endpoint 462corresponding to the eNB S1-U address, and second tunnel endpoint 464corresponding to the PGW S5-U address. Packet data received at eitherend can be encapsulated into a payload and directed to the correspondingaddress of the other end of the tunnel. Such direct tunneling avoidsprocessing, e.g., by SGW 420 that would otherwise relay packets betweenthe same two endpoints, e.g., according to a protocol, such as the GTP-Uprotocol.

In some scenarios, direct tunneling solution 458 can forward user planedata packets between eNB 416 a and PGW 426, by way of SGW 420. That is,SGW 420 can serve a relay function, by relaying packets between twotunnel endpoints 416 a, 426. In other scenarios, direct tunnelingsolution 458 can forward user data packets between eNB 416 a and PGW426, by way of the S1 U+ interface, thereby bypassing SGW 420.

Generally, UE 414 can have one or more bearers at any one time. Thenumber and types of bearers can depend on applications, defaultrequirements, and so on. It is understood that the techniques disclosedherein, including the configuration, management and use of varioustunnel solutions 450, 458, can be applied to the bearers on anindividual bases. That is, if user data packets of one bearer, say abearer associated with a VoIP service of UE 414, then the forwarding ofall packets of that bearer are handled in a similar manner. Continuingwith this example, the same UE 414 can have another bearer associatedwith it through the same eNB 416 a. This other bearer, for example, canbe associated with a relatively low rate data session forwarding userdata packets through core network 404 simultaneously with the firstbearer. Likewise, the user data packets of the other bearer are alsohandled in a similar manner, without necessarily following a forwardingpath or solution of the first bearer. Thus, one of the bearers may beforwarded through direct tunnel 458; whereas, another one of the bearersmay be forwarded through a two-tunnel solution 450.

Each WTRU 602 may be any type of device configured to operateor communicate in a wireless environment. For example, a WTRU maycomprise robot 106, mobile device 108, network device 300, or the like,or any combination thereof. By way of example, WTRUs 602 may beconfigured to transmit or receive wireless signals and may include a UE,a mobile station, a fixed or mobile subscriber unit, a pager, a cellulartelephone, a PDA, a smartphone, a laptop, a netbook, a personalcomputer, a wireless sensor, consumer electronics, or the like. It isunderstood that the exemplary devices above may overlap in theirfunctionality and the terms are not necessarily mutually exclusive.WTRUs 602 may be configured to transmit or receive wireless signals overan air interface 614.

Telecommunication system 600 may also include one or more base stations616. Each of base stations 616 may be any type of device configured towirelessly interface with at least one of the WTRUs 602 to facilitateaccess to one or more communication networks, such as core network 606,PTSN 608, Internet 610, or other networks 612. By way of example, basestations 616 may be a base transceiver station (BTS), a Node-B, an eNodeB, a Home Node B, a Home eNode B, a site controller, an access point(AP), a wireless router, or the like. While base stations 616 are eachdepicted as a single element, it will be appreciated that base stations616 may include any number of interconnected base stations or networkelements.

RAN 604 may include one or more base stations 616, along with othernetwork elements (not shown), such as a base station controller (BSC), aradio network controller (RNC), or relay nodes. One or more basestations 616 may be configured to transmit or receive wireless signalswithin a particular geographic region, which may be referred to as acell (not shown). The cell may further be divided into cell sectors. Forexample, the cell associated with base station 616 may be divided intothree sectors such that base station 616 may include three transceivers:one for each sector of the cell. In another example, base station 616may employ multiple-input multiple-output (MIMO) technology and,therefore, may utilize multiple transceivers for each sector of thecell.

Base stations 616 may communicate with one or more of WTRUs 602 over airinterface 614, which may be any suitable wireless communication link(e.g., RF, microwave, infrared (IR), ultraviolet (UV), or visiblelight). Air interface 614 may be established using any suitable radioaccess technology (RAT).

More specifically, as noted above, telecommunication system 600 may be amultiple access system and may employ one or more channel accessschemes, such as CDMA, TDMA, FDMA, OFDMA, SC-FDMA, or the like. Forexample, base station 616 in RAN 604 and WTRUs 602 connected to RAN 604may implement a radio technology such as Universal MobileTelecommunications System (UMTS) Terrestrial Radio Access (UTRA) thatmay establish air interface 614 using wideband CDMA (WCDMA). WCDMA mayinclude communication protocols, such as High-Speed Packet Access (HSPA)or Evolved HSPA (HSPA+). HSPA may include High-Speed Downlink PacketAccess (HSDPA) or High-Speed Uplink Packet Access (HSUPA).

As another example base station 616 and WTRUs 602 that are connected toRAN 604 may implement a radio technology such as Evolved UMTSTerrestrial Radio Access (E-UTRA), which may establish air interface 614using LTE or LTE-Advanced (LTE-A).

Optionally base station 616 and WTRUs 602 connected to RAN 604 mayimplement radio technologies such as IEEE 602.16 (i.e., WorldwideInteroperability for Microwave Access (WiMAX)), CDMA2000, CDMA2000 1×,CDMA2000 EV-DO, Interim Standard 2000 (IS-2000), Interim Standard 95(IS-95), Interim Standard 856 (IS-856), GSM, Enhanced Data rates for GSMEvolution (EDGE), GSM EDGE (GERAN), or the like.

Base station 616 may be a wireless router, Home Node B, Home eNode B, oraccess point, for example, and may utilize any suitable RAT forfacilitating wireless connectivity in a localized area, such as a placeof business, a home, a vehicle, a campus, or the like. For example, basestation 616 and associated WTRUs 602 may implement a radio technologysuch as IEEE 602.11 to establish a wireless local area network (WLAN).As another example, base station 616 and associated WTRUs 602 mayimplement a radio technology such as IEEE 602.15 to establish a wirelesspersonal area network (WPAN). In yet another example, base station 616and associated WTRUs 602 may utilize a cellular-based RAT (e.g., WCDMA,CDMA2000, GSM, LTE, LTE-A, etc.) to establish a picocell or femtocell.As shown in FIG. 6, base station 616 may have a direct connection toInternet 610. Thus, base station 616 may not be required to accessInternet 610 via core network 606.

RAN 604 may be in communication with core network 606, which may be anytype of network configured to provide voice, data, applications, and/orvoice over internet protocol (VoIP) services to one or more WTRUs 602.For example, core network 606 may provide call control, billingservices, mobile location-based services, pre-paid calling, Internetconnectivity, video distribution or high-level security functions, suchas user authentication. Although not shown in FIG. 6, it will beappreciated that RAN 604 or core network 606 may be in direct orindirect communication with other RANs that employ the same RAT as RAN604 or a different RAT. For example, in addition to being connected toRAN 604, which may be utilizing an E-UTRA radio technology, core network606 may also be in communication with another RAN (not shown) employinga GSM radio technology.

Core network 606 may also serve as a gateway for WTRUs 602 to accessPSTN 608, Internet 610, or other networks 612. PSTN 608 may includecircuit-switched telephone networks that provide plain old telephoneservice (POTS). For LTE core networks, core network 606 may use IMS core614 to provide access to PSTN 608. Internet 610 may include a globalsystem of interconnected computer networks or devices that use commoncommunication protocols, such as the transmission control protocol(TCP), user datagram protocol (UDP), or IP in the TCP/IP internetprotocol suite. Other networks 612 may include wired or wirelesscommunications networks owned or operated by other service providers.For example, other networks 612 may include another core networkconnected to one or more RANs, which may employ the same RAT as RAN 604or a different RAT.

Some or all WTRUs 602 in telecommunication system 600 may includemulti-mode capabilities. That is, WTRUs 602 may include multipletransceivers for communicating with different wireless networks overdifferent wireless links. For example, one or more WTRUs 602 may beconfigured to communicate with base station 616, which may employ acellular-based radio technology, and with base station 616, which mayemploy an IEEE 802 radio technology.

FIG. 7 is an example system 400 including RAN 604 and core network 606that may implement on-demand virtualization of robots. As noted above,RAN 604 may employ an E-UTRA radio technology to communicate with WTRUs602 over air interface 614. RAN 604 may also be in communication withcore network 606.

RAN 604 may include any number of eNode-Bs 702 while remainingconsistent with the disclosed technology. One or more eNode-Bs 702 mayinclude one or more transceivers for communicating with the WTRUs 602over air interface 614. Optionally, eNode-Bs 702 may implement MIMOtechnology. Thus, one of eNode-Bs 702, for example, may use multipleantennas to transmit wireless signals to, or receive wireless signalsfrom, one of WTRUs 602.

Each of eNode-Bs 702 may be associated with a particular cell (notshown) and may be configured to handle radio resource managementdecisions, handover decisions, scheduling of users in the uplink ordownlink, or the like. As shown in FIG. 7 eNode-Bs 702 may communicatewith one another over an X2 interface.

Core network 606 shown in FIG. 7 may include a mobility managementgateway or entity (MME) 704, a serving gateway 706, or a packet datanetwork (PDN) gateway 708. While each of the foregoing elements aredepicted as part of core network 606, it will be appreciated that anyone of these elements may be owned or operated by an entity other thanthe core network operator.

MME 704 may be connected to each of eNode-Bs 702 in RAN 604 via an S1interface and may serve as a control node. For example, MME 704 may beresponsible for authenticating users of WTRUs 602, bearer activation ordeactivation, selecting a particular serving gateway during an initialattach of WTRUs 602, or the like. MME 704 may also provide a controlplane function for switching between RAN 604 and other RANs (not shown)that employ other radio technologies, such as GSM or WCDMA.

Serving gateway 706 may be connected to each of eNode-Bs 702 in RAN 604via the S1 interface. Serving gateway 706 may generally route or forwarduser data packets to or from the WTRUs 602. Serving gateway 706 may alsoperform other functions, such as anchoring user planes duringinter-eNode B handovers, triggering paging when downlink data isavailable for WTRUs 602, managing or storing contexts of WTRUs 602, orthe like.

Serving gateway 706 may also be connected to PDN gateway 708, which mayprovide WTRUs 602 with access to packet-switched networks, such asInternet 610, to facilitate communications between WTRUs 602 andIP-enabled devices.

Core network 606 may facilitate communications with other networks. Forexample, core network 606 may provide WTRUs 602 with access tocircuit-switched networks, such as PSTN 608, such as through IMS core614, to facilitate communications between WTRUs 602 and traditionalland-line communications devices. In addition, core network 606 mayprovide the WTRUs 602 with access to other networks 612, which mayinclude other wired or wireless networks that are owned or operated byother service providers.

FIG. 8 depicts an overall block diagram of an example packet-basedmobile cellular network environment, such as a GPRS network, that mayimplement on-demand virtualization of robots as described herein. In theexample packet-based mobile cellular network environment shown in FIG.8, there are a plurality of base station subsystems (BSS) 800 (only oneis shown), each of which comprises a base station controller (BSC) 802serving a plurality of BTSs, such as BTSs 804, 806, 808. BTSs 804, 806,808 are the access points where users of packet-based mobile devicesbecome connected to the wireless network. In example fashion, the packettraffic originating from mobile devices is transported via anover-the-air interface to BTS 808, and from BTS 808 to BSC 802. Basestation subsystems, such as BSS 800, are a part of internal frame relaynetwork 810 that can include a service GPRS support nodes (SGSN), suchas SGSN 812 or SGSN 814. Each SGSN 812, 814 is connected to an internalpacket network 816 through which SGSN 812, 814 can route data packets toor from a plurality of gateway GPRS support nodes (GGSN) 818, 820, 822.As illustrated, SGSN 814 and GGSNs 818, 820, 822 are part of internalpacket network 816. GGSNs 818, 820, 822 mainly provide an interface toexternal IP networks such as PLMN 824, corporate intranets/internets826, or Fixed-End System (FES) or the public Internet 828. Asillustrated, subscriber corporate network 826 may be connected to GGSN820 via a firewall 830. PLMN 824 may be connected to GGSN 820 via aboarder gateway router (BGR) 832. A Remote Authentication Dial-In UserService (RADIUS) server 834 may be used for caller authentication when auser calls corporate network 826.

Generally, there may be a several cell sizes in a network, referred toas macro, micro, pico, femto or umbrella cells. The coverage area ofeach cell is different in different environments. Macro cells can beregarded as cells in which the base station antenna is installed in amast or a building above average roof top level. Micro cells are cellswhose antenna height is under average roof top level. Micro cells aretypically used in urban areas. Pico cells are small cells having adiameter of a few dozen meters. Pico cells are used mainly indoors.Femto cells have the same size as pico cells, but a smaller transportcapacity. Femto cells are used indoors, in residential or small businessenvironments. On the other hand, umbrella cells are used to covershadowed regions of smaller cells and fill in gaps in coverage betweenthose cells.

FIG. 9 illustrates an architecture of a typical GPRS network 900 thatmay implement on-demand virtualization of robots as described herein.The architecture depicted in FIG. 9 may be segmented into four groups:users 902, RAN 904, core network 906, and interconnect network 908.Users 902 comprise a plurality of end users, who each may use one ormore devices 910. Note that device 910 is referred to as a mobilesubscriber (MS) in the description of network shown in FIG. 9. In anexample, device 910 comprises a communications device (e.g., mobiledevice 108, robot 106, mobile positioning center 116, network device300, any of detected devices 500, second device 508, access device 604,access device 606, access device 608, access device 610 or the like, orany combination thereof). Radio access network 904 comprises a pluralityof BSSs such as BSS 912, which includes a BTS 914 and a BSC 916. Corenetwork 906 may include a host of various network elements. Asillustrated in FIG. 9, core network 906 may comprise MSC 918, servicecontrol point (SCP) 920, gateway MSC (GMSC) 922, SGSN 924, home locationregister (HLR) 926, authentication center (AuC) 928, domain name system(DNS) server 930, and GGSN 932. Interconnect network 908 may alsocomprise a host of various networks or other network elements. Asillustrated in FIG. 9, interconnect network 908 comprises a PSTN 934, anFES/Internet 936, a firewall 1038, or a corporate network 940.

An MSC can be connected to a large number of BSCs. At MSC 918, forinstance, depending on the type of traffic, the traffic may be separatedin that voice may be sent to PSTN 934 through GMSC 922, or data may besent to SGSN 924, which then sends the data traffic to GGSN 932 forfurther forwarding.

When MSC 918 receives call traffic, for example, from BSC 916, it sendsa query to a database hosted by SCP 920, which processes the request andissues a response to MSC 918 so that it may continue call processing asappropriate.

HLR 926 is a centralized database for users to register to the GPRSnetwork. HLR 926 stores static information about the subscribers such asthe International Mobile Subscriber Identity (IMSI), subscribedservices, or a key for authenticating the subscriber. HLR 926 alsostores dynamic subscriber information such as the current location ofthe MS. Associated with HLR 926 is AuC 928, which is a database thatcontains the algorithms for authenticating subscribers and includes theassociated keys for encryption to safeguard the user input forauthentication.

In the following, depending on context, “mobile subscriber” or “MS”sometimes refers to the end user and sometimes to the actual portabledevice, such as a mobile device, used by an end user of the mobilecellular service. When a mobile subscriber turns on his or her mobiledevice, the mobile device goes through an attach process by which themobile device attaches to an SGSN of the GPRS network. In FIG. 9, whenMS 910 initiates the attach process by turning on the networkcapabilities of the mobile device, an attach request is sent by MS 910to SGSN 924. The SGSN 924 queries another SGSN, to which MS 910 wasattached before, for the identity of MS 910. Upon receiving the identityof MS 910 from the other SGSN, SGSN 924 requests more information fromMS 910. This information is used to authenticate MS 910 together withthe information provided by HLR 926. Once verified, SGSN 924 sends alocation update to HLR 926 indicating the change of location to a newSGSN, in this case SGSN 924. HLR 926 notifies the old SGSN, to which MS910 was attached before, to cancel the location process for MS 910. HLR926 then notifies SGSN 924 that the location update has been performed.At this time, SGSN 924 sends an Attach Accept message to MS 910, whichin turn sends an Attach Complete message to SGSN 924.

Next, MS 910 establishes a user session with the destination network,corporate network 940, by going through a Packet Data Protocol (PDP)activation process. Briefly, in the process, MS 910 requests access tothe Access Point Name (APN), for example, UPS.com, and SGSN 924 receivesthe activation request from MS 910. SGSN 924 then initiates a DNS queryto learn which GGSN 932 has access to the UPS.com APN. The DNS query issent to a DNS server within core network 906, such as DNS server 930,which is provisioned to map to one or more GGSNs in core network 906.Based on the APN, the mapped GGSN 932 can access requested corporatenetwork 940. SGSN 924 then sends to GGSN 932 a Create PDP ContextRequest message that contains necessary information. GGSN 932 sends aCreate PDP Context Response message to SGSN 924, which then sends anActivate PDP Context Accept message to MS 910.

Once activated, data packets of the call made by MS 910 can then gothrough RAN 904, core network 906, and interconnect network 908, in aparticular FES/Internet 936 and firewall 1038, to reach corporatenetwork 940.

The improved performance of the E-UTRAN 1018 relativeto a typical UMTS network allows for increased bandwidth, spectralefficiency, and functionality including, but not limited to, voice,high-speed applications, large data transfer or IPTV, while stillallowing for full mobility.

Typically MS 1002 may communicate with any or all of BSS 1004, RNS 1012,or E-UTRAN 1018. In a illustrative system, each of BSS 1004, RNS 1012,and E-UTRAN 1018 may provide MS 1002 with access to core network 1010.Core network 1010 may include of a series of devices that route data andcommunications between end users. Core network 1010 may provide networkservice functions to users in the circuit switched (CS) domain or thepacket switched (PS) domain. The CS domain refers to connections inwhich dedicated network resources are allocated at the time ofconnection establishment and then released when the connection isterminated. The PS domain refers to communications and data transfersthat make use of autonomous groupings of bits called packets. Eachpacket may be routed, manipulated, processed or handled independently ofall other packets in the PS domain and does not require dedicatednetwork resources.

The circuit-switched MGW function (CS-MGW) 1026 is part of core network1010, and interacts with VLR/MSC server 1028 and GMSC server 1030 inorder to facilitate core network 1010 resource control in the CS domain.Functions of CS-MGW 1026 include, but are not limited to, mediaconversion, bearer control, payload processing or other mobile networkprocessing such as handover or anchoring.

Example data stored by HSS 1042 include, but is not limitedto, user identification, numbering or addressing information, securityinformation, or location information. HSS 1042 may also provide call orsession establishment procedures in both the PS and CS domains.

VLR/MSC Server 1028 provides user location functionality. When MS 1002enters a new network location, it begins a registration procedure. A MSCserver for that location transfers the location information to the VLRfor the area. A VLR and MSC server may be located in the same computingenvironment, as is shown by VLR/MSC server 1028, or alternatively may belocated in separate computing environments. A VLR may contain, but isnot limited to, user information such as the IMSI, the Temporary MobileStation Identity (TMSI), the Local Mobile Station Identity (LMSI), thelast known location of the mobile station, or the SGSN where the mobilestation was previously registered. The MSC server may containinformation such as, but not limited to, procedures for MS 1002registration or procedures for handover of MS 1002 to a differentsection of core network 1010. GMSC server 1030 may serve as a connectionto alternate GMSC servers for other MSs in larger networks.

EIR 1044 is a logical element which may store the IMEI for MS 1002. Userequipment may be classified as either “white listed” or “black listed”depending on its status in the network. If MS 1002 is stolen and put touse by an unauthorized user, it may be registered as “black listed” inEIR 1044, preventing its use on the network. A MME 1046 is a controlnode which may track MS 1002 or UE 1024 if the devices are idle.Additional functionality may include the ability of MME 1046 to contactidle MS 1002 or UE 1024 if retransmission of a previous session isrequired.
